Popular Australian Bed Sizes

Queen Bed Size Australia

A Queen mattress in Australia is 153 × 203 cm, or 1530 × 2030 mm. It is one of the most common choices for couples because it gives more space than a Double while still fitting many standard Australian bedrooms.

A Queen suits couples, solo sleepers who want more room, guest rooms and main bedrooms. It is also easy to pair with standard bedding, protectors and a matching Queen bed frame .

Best for: couples, main bedrooms, apartments, guest rooms and solo sleepers who like extra space.

King Bed Size Australia

A King mattress in Australia is 183 × 203 cm, or 1830 × 2030 mm. It has the same length as a Queen but gives 30 cm more width, making it better for couples who want more room to move.

Best for: couples, larger bedrooms, shared sleeping with kids or pets, and sleepers who want more width.

Double Bed Size Australia

A Double mattress in Australia is 138 × 188 cm, or 1380 × 1880 mm. It is wider than a King Single but shorter and narrower than a Queen.

A Double suits solo adults, teenagers and guest rooms. It can fit two people for short stays, but for everyday couple use, a Queen is usually more comfortable because it gives extra width and length. Pair it with a matching Double bed frame for the cleanest fit.

Best for: teens, tall kids, solo adults, guest rooms and compact bedrooms.

Single Bed Size Australia

Long Single Bed Size Australia

Best for: taller solo sleepers, narrow bedrooms and guest rooms.

Super King Bed Size Australia

A Super King mattress in Australia is 203 × 203 cm, or 2030 × 2030 mm. It is the largest common mattress size in Australia.

A Super King gives maximum sleeping space, but it needs a large bedroom. Before buying, measure the room, doorways, hallway and stairs, and check that bedding is available in the right size.

Best for: large main bedrooms, couples wanting maximum space, families who share the bed on weekends and people who prefer a wide sleep surface.

Bed Size vs Mattress Size vs Bed Frame Size

People often use "bed size" and "mattress size" as if they mean the same thing, but there can be a difference.

Mattress size means the sleeping surface itself. For example, a Queen mattress in Australia measures 153 × 203 cm.

Bed size can mean the full outside size of the bed frame. This may include the headboard, rails, storage drawers, gas lift base or outer platform.

Before buying, check both the mattress dimensions and full bed frame dimensions. A mattress may fit the frame, but the full bed may still feel too large in the room. For smaller rooms, bed frames with storage can help reduce clutter.

Which Bed Size Should You Choose?

The right bed size depends on who uses the bed, the size of the room, body height, sleeping style and how much furniture you need around the bed.

If you are buying for long-term use, choose the largest size your room can comfortably handle. The bed should not block doors, wardrobes, drawers or walking paths.

Bed Size by Bedroom Size

Small Bedroom

A small bedroom is usually better suited to a Single, Long Single or King Single bed. A Double can work in some small rooms, but only if there is enough space for a walkway, wardrobe access and bedside storage.

Recommended sizes: Single, Long Single, King Single.

Standard Bedroom

A standard bedroom (around 4.2 × 3.9 m) can often fit a Double or Queen bed. A Queen is usually the better option for couples because it gives more width and length than a Double.

Recommended sizes: Double or Queen.

Large Bedroom

A large bedroom can usually fit a Queen, King or Super King bed. A King gives couples more width, while a Super King creates the largest sleep surface.

Recommended sizes: Queen, King or Super King.

How Much Space Should You Leave Around a Bed?

Try to leave around 60–90 cm of walking space around the bed where possible. This makes the room easier to use and helps with access to doors, wardrobes, windows, drawers and bedside tables.

Before buying a larger mattress, measure:

If your room has limited storage, pair the bed with compact bedside tables or a chest of drawers that leaves enough walking room.

Australian vs US and UK Bed Sizes

Australian bed sizes are not always the same as US or UK bed sizes. If you are buying a mattress, bed frame, bedding or sheets from an overseas brand, always check the exact measurements in centimetres or millimetres. read detailed guide here

If your mattress, bed frame and bedding come from different brands or countries, check all measurements before purchase. This is especially important when buying fitted sheets, mattress protectors or overseas bedding sets.

Mattress Height and Fitted Sheet Depth

Mattress length and width are not the only measurements that matter. Mattress height can affect fitted sheets, bed frame fit and the final height of the bed.

A thicker mattress may need deeper fitted sheets. It can also sit higher on a frame, which may change how easy it is to get in and out of bed. If you are buying bed sheets , check the mattress size and mattress depth before purchase.
